Abstract
We compare the coronal transient wave phenomenon discovered by SOHO extreme ultraviolet observations ("'EIT waves") wi-th the associated radio signatu re of a coronal shock wave (type II burst). 90% of the type II bursts are a ssociated with an EIT wave. On average, the speed derived from the radio bu rst is about three times larger than the EIT wave speed. Within the sample, there is no correlation between the speeds of both tracers of a coronal di sturbance, Under very general assumptions we conclude that both wave phenom ena can be different signatures of the same fast magnetosonic disturbance.
